Husband suddenly left to go 'home'

I have been living with my partner for 8 years, married for two. He is english lm Australian he is English. We lived together in England 7 and moved to Australia last year. We have had a hard time in Australia with him losing a couple of very well paying jobs, and moving 4 times and him hurting his back, preventing him from working. I thought we had a good relationship but then last week after home being away for two weeks he came back and said he was going back to England. In two days. We both got upset and did the accusing thing but eventually decided that he would go back and we would be in contact everyday. Fine for the first day, he sent me two emails but then he went to visit his father and he has not contacted me for 5 days. .???? I have sent the first email to which he didnt reply then another to ask if he is ok. I know he has read them as l know his email password. But no reply. His father does not like me as l will not be manipulated by him and have only spoken to him twice since our wedding ( well he did tell me it was the worst wedding he had ever been to, and had no idea why anybody would marry me plus more). His father is very manipulative which my husband can't see, he is a complete narcissist. I just don't know what to do. My blood pressure is through the roof and if l wasn't so agitated ld be depressed.
